Chemical compositions of petals of Chrysanthemum spp. were determined to renew its interest as a food material. The moisture contents of wild Chrysanthemum boreale and holticulturized Chrysanthemum morifolium were 11.7% and 11.0%. The proximate chemical ompositions were 6.1% and 11.7% in protein, 3.7% and 5.2% in ash, 11.1% and 12.8% in reducing sugar, of C. boreale and C. morifolium, respectively. Free sugars were mainly composed of fructose, glucose and sucrose. In fatty acid composition, the ratios of saturated to unsaturated fatty acids were 1.2:1 and 3.0:1, respectively. The amino acids determined were found 0.18 and 0.26 in the ratio of essential to total amino acids in each sample. Major elements of Chrysanthemum petals were Ca, K, Fe, Mg and Na, but the contents of Ca and Fe were more than twice higher in C. boreale than c. morifolium, Major volatile flavor components were 28.22% of epi-bicyclophellandrene and 24.55% of camphor in C. boreale, and 14.24% of 4-methyl-1-(10methylethyl)-3-cyclhexen-1-ol, 10.74% of camphor and 7.64% of 1,8-cineol in C. morifolium.

Effects of three kinds of precursors as well as exogenous taxanes on the production of taxol and its derivatives were investigated in Taxus cuspidata and Taxus brevifolia cell suspension cultures. When geraniol was added as a precursor of geranylgeranyl pyrophosphate to enhance diterpenoid metabolism, production of some taxanes including taxol was enhanced. The time of addition and amount of feeding were found to be important factors. Feeding of camphor and menthol resulted in negative effects on taxol production. Influences of exogenous taxanes on taxane production by cell cultures were found to be very complicated. When taxol, baccatin III, cephalomannine were exogenously added into the culture, production of baccatin III, 7-epi-10-deacetyltaxol, 10-deacetyltaxol was increased respectively.

The conjugally transferred TOL plasmid or NAH plasmid was stably maintained and expressed in n-alkane assimilating Pseudomonas putida KCTC 2405. However, these plasmids were not able to coexist in this strain because of incompatibility. The incompatibility of TOL and NAH plasmid was bypassed using CAM::TOL* plasmid, which was constructed by the transposition of only tol gene without incompatibility system in TOL plasmid into CAM plasmid. p. putida 3SK capable of growing on m-toluate, naphthalene, camphor, and n-alkane(C8-C24) was constructed by the conjugal transfer of NAH plasmid into n-alkane assimilating p. putida SK carrying CAM:: TOL* plasmid. CAM::TOL＊ plasmid in p. putida 3SK was stable on the selective media but unstable on the nonselective media.

The present study demonstrates the effect of solidification condition on the pore structure in freeze drying process using the slurries of CuO/sublimable vehicles. Camphene and Camphor-45 wt% naphthalene based slurries with 14 vol% CuO powder were frozen into a mold at $-25^{\circ}C$, followed by sublimation at room temperature. The green bodies were hydrogen-reduced and sintered at $500^{\circ}C$ for 1 h. The porous Cu specimen, frozen the CuO/camphene slurry into the heated mold of the upper part, showed large pores with unidirectional pore channels and small pores in their internal wall. Also, it was observed that the size of large pores was decreasing near the bottom part of specimen. The change of pore structure depending on the freezing condition was explained by the nucleation behavior of camphene crystals and rearrangement of solid powders during solidification. In case of porous Cu prepared from CuO/Camphor-naphthalene system, the pore structure exhibited plate shape as a replica of the original structure of crystallized vehicles with hypereutectic composition.

In this study, we identified the volatile compounds of Artemisia princeps Pampan. cv. ssajuari (ssajuarissuk) essential oils and analyzed changes in the contents of volatile compounds under four different storage conditions, such as exposure to air at $20^{\circ}C$ and $40^{\circ}C$. Sixty-five volatile compounds consisting of 6 monoterpene hydrocarbons, 23 oxygenated monoterpenes, 16 sesquiterpene hydrocarbons, 6 oxygenated sesquiterpenes, 1 diterpene, 6 benzene derivatives, and 7 non-isoprenoid compounds were identified on the basis of their mass spectra characteristics and retention indices from original ssajuarissuk essential oils. Identified compounds constituted 90.56% of the total peak area. Borneol (10.29%) was the most abundant compound in the original ssajuarissuk essential oils, followed by 1,8-cineole (9.06%), viridiflorol (8.99%), spathulenol (8.73%), $\alpha$-thujone (5.28%), and camphor (4.39%). After six months storage at $40^{\circ}C$ with the cap opened for 3 min everyday, the total amount of volatile compounds in essential oil as determined by the percentage peak area decreased by 84.93%. The total levels of cis-sabinene hydrate, camphor, 4-terpineol, humulene oxide, $\beta$-caryophyllene oxide, and caryophyllene alcohol increased significantly. For ssajuarissuk essential oils stored under experimental conditions, changes in the contents of volatile compounds in essential oils were accelerated by temperature and contact with the atmosphere.

The effect of sublimable vehicles on the pore structure of Cu fabricated by freeze drying is investigated. The 5 vol% CuO-dispersed slurries with camphene and various camphor-naphthalene compositions are frozen in a Teflon mold at -25℃, followed by sublimation at room temperature. After hydrogen reduction at 300℃ and sintering at 600 ℃, the green bodies of CuO are completely converted to Cu with various pore structures. The sintered samples prepared using CuO/camphene slurries show large pores that are aligned parallel to the sublimable vehicle growth direction. In addition, a dense microstructure is observed in the bottom section of the specimen where the solidification heat was released, owing to the difference in the solidification behavior of the camphene crystals. The porous Cu shows different pore structures, such as dendritic, rod-like, and plate shaped, depending on the composition of the camphornaphthalene system. The change in pore structure is explained by the crystal growth behavior of primary camphor and eutectic and primary naphthalene.

Parched mugwort tea was manufactured from mugwort (Artemisia asicatica nakai) leaves by traditional green tea preparation method. Volatile flavor compounds were collected by Tenax GC and they separated on DB-5 capillary column ($60m\;\times\;0.25mm$ i.d.) Fifty eight compounds were isolated and identified by GC-MS from the volatiles. Eleven compounds incucluding benzaldehyde, pinene, myrcene, cineole, 2-phrrolidinonoe, camphor, thujong, 1-acetylpiperidine, caryophyllene, coumarin, and farnesol among the compounds identified were considered as important compounds contributing mugwort-like flavor to the parched mugwort tea. The mixture of these eleven authentic compounds could reproduce aroma of mugwort leaves harvested in April. As results, the concentrations of these eleven flavor compounds in parched mugwort tea may indicate the strength of mugwort-like aroma of the tea.

GC-MS data on the volatile oil (CS-oil) of Chrysanthemum sibiricum herbs led to the identification of 2-methoxythioanisol, (+)-camphor, geraniol, citral, thymol, eugenol, ${\beta}-caryophyllene$ oxide, ${\beta}-caryophyllene$, ${\beta}-eudesmol$, juniper camphor together with an unknown substance using the mass spectral library and literature data. CS-oil exhibited significant cytotoxicities on HL-60 $(IC_{50}\;12.5\;{\mu}g/ml)$ cell and mild on HepG-2 cell $(IC_{50}\;102.4\;{\mu}g/ml)$, though the antioxidant ability was found not to be potent $(IC_{50}\;97.2\;{\mu}g/ml)$. However, the component eugenol showed potent antioxidant ability but mild cytotoxicity. Methyleugenol with no phenolic OH showed less potent cytotoxic and antioxidative properties than eugenol suggesting that phenolic OH plays an important role for the cytotoxic and antioxidant abilities. The oil-pretreatment prevented lipid peroxidation induced by bromobenzene in the rat. Therefore, it was demonstrated that CS-oil could be a cytotoxic agent with antioxidant properties.
